Queensland has recorded one locally acquired case in the past four days, with Premier Annastacia Palaszczuk saying social distancing restrictions and an outdoor face mask mandate can ease from 4pm on Friday.

“We have some good news for Queenslanders and I really want to thank everybody for doing the right thing and today we have zero community cases in Queensland, so well done Queensland. Fantastic job,” she told reporters on Wednesday.

The premier said an outdoor face mask mandate would end at 4pm on Friday, but masks will need to continue being worn indoors.

“So this is really important, this is our added protection against the Delta variant, and I think it’s a small price to pay for some easing our restrictions,” Palaszczuk said.

Up to 30 people will be allowed to gather at private homes and 100 people will be allowed at weddings and funerals.

Indoor events and stadiums with ticketed seating will be allowed to operate at 75 per cent capacity and community sport will be allowed to restart.

Social distancing rules in cafes and restaurants will be reviewed next week.

However, Palaszczuk left no doubt of a looming threat from the Delta’s march northwards  from NSW, insisting the border between the two states will be tightened after an explosion of cases there.

Announcing NSW had recorded 633 new locally acquired cases on Wednesday, that state’s premier Premier Gladys Berejiklian said “we haven’t seen the worst of it”.

“According to the data we have every person who has the virus spreading it to at least more than one person,” she said.

Only police, health workers and construction workers who have had one dose of a vaccine are allowed to cross into Queensland.

“There are too many people crossing the border, so that means we want to put even tighter restrictions on our border,” Palaszczuk said.

“It only takes one person crossing the border with Delta and we’re into a lockdown.

“Now I don’t want that and I know Queenslanders don’t want that.”

Chief Health Officer Jeannette Young said there would be a widespread review later this week of which workers who live in NSW are really “essential” for Queensland.

The director-general of the premier’s department Rachel Hunter will conduct the review.

Young said the review will be completed later this week and new border restrictions would come into effect next week.

She said border closures and lockdowns remain the best health responses to outbreaks until 70 per cent of the population is vaccinated.

“Then people will be able to go about their lives,” she said.

“Otherwise, I can see in the future that the people who aren’t vaccinated, are going to have to minimise their lives to protect their own health and safety.”

Deputy Police Commissioner Steve Gollschewski said 5700 vehicles were intercepted at the borders on Tuesday, down from 7700 on Monday.

He said 513 cars were turned back to NSW on Tuesday, down from 1090 on Monday.

Gollschewski said police would not stop the “very rigid application” of public health orders.

“We’re hearing lots of sad stories around how this impacts on people. I’m terribly sorry about that; we are going to continue to do that,” he said.

“You must meet the requirements to enter the state or you’re simply not entering.”

The entire state of NSW is locked down with tight restrictions but authorities are concerned that 70 per cent of transmission is occurring in homes.

The likelihood of household transmission is reduced by about 50 per cent by three to four weeks after vaccination.
